The IWS Image Library contains
images of aquatic organisms from the Pacific
Northwest. These images may be used for noncommercial,
educational purposes as described in our
license agreement.
The images are organized into convenient
categories rather than a strict taxonomic hierarchy.
All identifications are done to the best of our ability
based on recently published taxonomic keys, but may not represent
the most recent nomenclature due to the rapidly
changing nature of taxonomy.

How to browse the images:

Select a group of algae by clicking on a group
and then a subgroup.

A sample of images in the subgroup will appear below.

Click on one of the sample thumbnails to view a full
size gallery of all algae images in your selected group.
